Hi guys it's been awhile since I was last here... but nonetheless, I wanted to say...
I actually own a beautiful all matching date stamp(s) April 1969 Sonor Rosewood Teardrop 18x14/12/14 bop kit with matching Rosewood 5x14 snare drum.
No joke they sound truly amazing! She is definitely one of a kind... but if, I remember correctly their were at least two more Rosewood bop kits exactly like mine worldwide... but they were 1970 date stamps.
My friend has a set that he has had since he was a kid in the early 70's. They are natural wood. I will get some pics next time our paths cross.....and NO he won't sell them, I have been trying for years. lol
